IMPROVEMENT IN AUTOMATIC GATES.

Specification forming part of Letters Patent No, 216,959, dated July 1,1879; application led April 16, 1879.

To all whom it may concern:

Be it known that I, WILLIAM J. HUrcHINs, of the city of Joliet, Willcounty, and State of Illinois, have invented certain Improvements inAutomatic Gates, the construction and op eration of which I will proceedto explain, reference being had to the annexed drawings, making a partof this specification, in which- Figures l and 2 are side elevations.Figs, 3 and 7 are plan views on the top. Fig. 4L is ran end view.A Figs.5 and 6 are perspective views; and Fig. 8, a general perspective view,showing the gate partially open.

The object of my invention consists in so constructing a gate that itmay be operated by means of the wheel of a vehicle without alighting.The working parts ofthe gate are above ground, and the gate Will foldback out of the Way from obstacles.

In the drawings, A represents the folding gate; B, the supportingpost;C, the case-post for the gate A to fold back into, and D represents themovable case-post for the outer end ofthe gate A to rest in when closed,as shown in Fig. 1.

L represents a sliding plate fastened to the upper end of the bar of therst joint of the gate A, and held in place by means of a bolt in theslot of said plate, and the lower end of the bar of the first joint ofthe gate A is held in place by means of the bolt w, as shown in Figs.land 2.

Y c represents the locking slide-bar, one end of whichis attached nearthe last central joint of the gate A, while the other end rests andslides on the friction-roller t, as represented in Figs. 1, 2, and 5. l

H represents the crank attached upright to the post B, and held in placeby the clasps e.

Rrepresents an arm attached at one end to the upper end of the crank H,while the other end of which is attached to the second vcentral joint ofthe gate A by means of the journal o, as shown in Figs. l and 5. l

P' represents a segmental cog attached to the lower end of the crank H,and P a similar cog, placed so as its cogs will mesh into the cogs ofP', as shown in Figs. 3 and 7.

T' represents a lever attached to the cog P, as shown in Figs. 1 and 7.

crepresents the lock attached to the post F, the outer and lower part ofsaid lock resting on the sliding bar c when the gate A is open, and whenthe gate A is closed said portion rests in the notch z of the lockingslidebar a, and is held in place by means of the spring d, to preventthe gate from opening, as shown in Figs. 4. and 5,. Y

K represents a friction-roller attached to the inner side of thecase-post C, for the slide B or a to slide against, as shown in Fig. 6and by the dotted lines in Figs. l and 2.

S represents a double crank -supplied with the lever M, and connectedwith the lever T' by means of the rod N; and S represents a seconddouble crank provided with the lever M', and connected to the reverselever T by means of the rod N', as shown in Figs. 3 and 7.

n represents the sliding bars, oneV end of which is attached to thecase-post D, while the other end may slide back through the mortises inthe post E, thus giving a wider passage, when desired, as shown in Fig.2.

The gate A may be made from wood or iron. Each bar is provided withholes, and either bolted or riveted together.

Fig. 1 represents the gate A when closed, and Fig. 2 represents saidgate when open, folded back into the case-post C.

It will be observed that when the cranks S and S are operated the leversM and M' -are also operated, thus operating the rods N and N', whichoperate the cogs P and P', by means of the levers T and T'. By thismeans the crank and arm B are operated, thus opening and closing thegate A at pleasure.

It will also be observed that when the arm R draws on the gate A theouter end of said gate is slightly elevated, and as it moves back 1t isgradually elevated until open, and when the gateA is closed the slidingbar a is level; but as the gate A opens the outer end, which is attachedto the gate A, is elevated with the gate 5 and when the bar a slidespast its center over the roller t the weight of its outer end causes itto support the outer end of the gate A, and assists in opening it as itruns downhill over the roller t'. The principal use of the bar a,however, is to give the gate strength laterally, guide it to shutstraight, and to lock it shut by means of the notch z and spring-lock c,as before stated.

Fig. 8 shows a general perspective view,

S', opening as you enter, and closing as you pass out, all withoutalighting.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is as follows, to wit:

1,. The combination of the segmental cogs P and P', reverse lever T,lever T', crank H, arm R, journal o, and folding gate A, arranged tooperate su bstantially as and for the purpose set forth.

2. The combination of the lock e, spring d,

crank H, arm R, and locking slide-bar a, provided with notch z, arrangedto operate in the manner and for the purpose set forth.

3. The combination of the movable post D, slide-bars n, and post E, forthe purpose set forth.

4. The combination of the folding gate A, slide-bar a, and the lock c,for the purpose set forth.

5. The combination of the folding gate A, sliding plate L, bolt x,locking slide-bar a, pro vided with notch z, frictioneroller i,frictionroller K, lock c, spring d, arm R, crank H, segmental cogs P andP', lever T', rods N and N', levers M and M', double cranks S and S',

post D, and slide-bars n, and post E, arranged to operate in the mannerand for the purpose set forth.
